If you go with a stealth character, you might want to use a dagger rather than a sword, axe or mace, due to its faster attack speed. I'm not familiar with the benefits of daggers though, so someone else will have to explain their use for a thief/assassin type of character. IIRC it mainly has to do with applying poisons with the dagger...and it's possible you might want to avoid daggers, because they apply poisons too fast. Can't remember for certain.
Magic use is totally up to you, and stealthy characters can make good use of Illusion and Restoration. Doesn't matter much if the skill is part of your build, just use spells you find useful -- for example, you don't have to have Mysticism as a major in order to use Detect Life. If it's a Major skill, it'll increase faster (especially good if you plan to use Restoration, which increases very slowly), and you'll get a couple free spells at the beginning. One trick is to use Alchemy, but don't make it a major skill; you can then make all the poisons and potions you want without leveling up your character too quickly, and still get plenty of magicka to cast the stronger spells.
Your plan to use bows is good, then a melee weapon up close. You can also do all the Mages Guild recommendations early just so you'll have access to the spellmaking and enchanting altars in the Arcane Uni, so you can make your own spells and enchantments and not have to worry about buying or finding them all the time (and no need to do the Mages Guild quests after that until you're ready to). When using a bow, use Alchemy to make poisons, poison your bow, then sneak when taking the first shot. You can also use various Illusion spells to prevent and control combat.
http://www.uesp.net/wiki/Oblivion:Races shows the stat differences between the races. If your main goal is the Thieves Guild and DB, you'll definitely want to focus on stealth, even if you play something like a warrior or mage -- being sneaky will be the most important trait :ph34r:
